    Abstract : Plant pathogenic phytoplasmas can infect hundreds of plant species and lead to enormous economic loss. To understand the interactions between phytoplasmas and their hosts, genome sequencing plays an important role. To date, ten phytoplasmaphytoplasmaSubject Category: Organism Names

    , ribosomal structure and biogenesis (75 genes) are the largest proportion. Interestingly, the predicted secreted proteins were not found in our core set, suggesting that these genes were diverse. In addition, a highly stringent strategy was taken to mine the group-specific genes among the five groups. Although the largest part was the hypothetical proteins, some putative secreted proteins (potential effectors) were identified. TENGU was selected to be one of the 16SrI group-specific genes. This may partly account for the diverse pathogenicitypathogenicitySubject Category: Properties
